After having spent a good deal of time at the Oliver factory, talking with the family and lots of time investigating the Casita - I feel very sure in saying that Oliver did not make a mold of a Casita. Some of the evidence:
- The boneyard of empty shells behind the factory of their initial tries from their hand carved mold attempts. The 17' Oliver mold was hand carved by trial and error. The 21', they actually had it CAD designed.
- The Oliver is a double hull construction, and the Casita is a single hull. The entire interior of the Oliver is molded, where as the interior of the Casita is riveted on.
- While at a quick glance they look quite similar, there are lots and lots of differences that you would see from comparing them side by side - from tank placement/size, connectors, wheel wells, propane
There is no doubt however that Oliver family was directly inspired by their years of Casita camping.
